IRWIN Screw Extractor for Spiral Screws, 5-Piece (53535)

I was working on my KTM motorcycle replacing the front sprocket when I snapped the bolt on the countershaft. Doh!! I was able to drill the hardened metal with my Irwin cobalt drill bits. (Another great Product) and I tried using some cheap easyouts which didn't work well at all because the bolt had lockite red on it. I knew this was going to be next to impossible to remove.I called my KTM dealer and they quoted me a replacement of the countershaft assembly and 8 hours of labor to split the engine case to replace the countershaft for $1200.00. I was like – No Way! So I started researching other options. I read on a forum where someone had the same exact issue as me and having success with this style of extractor.I found these here on Amazon and since they were Irwin brand which is a brand of quality tools I trust so I bought this $10 set of extractors. I got them the very next day I ordered them and I used one of the extractors and hammered it in as deep as it would go and it grabbed tight enough that I was able to remove the remaining bolt without touching the threads on the countershaft. Whoo Hoo!These work very well! Just buy a set, trust me they are worth having in your tool box!

I knew better! I have a 10mm bolt broken off and was able to drill through it. Used the smallest bit and dropped/lost it in gravel. Next one up? Re drilled and had NO problem until the screw metal gave way. Re drilled and made it go deeper. Using a quarter inch handle managed to grip tight enough but I broke it! The tool did was it was supposed to do! If your drilling 10mm? Just drill it out and Re tap! My bad. I knew this and did it anyway. I am NOT unhappy with the tool. It gripped and tried to work but just too small of my force and it broke! This is the nature of hardened steel. Now I am completely effed! Again MY BAD CUZ I KNEW BETTER! These are really nice extractors and certainly will do what I need in the future. Would I repurchase? Absolutely!Would I ever try such a small bolt? HE DOUBLE TOOTHPICK NO!

Not my favorite tool in the kit but how luck lined up, used it the day it came in. Buddy's lug nuts snapped off and it took a bit but this got it off. Still a pretty solid tool but not my favorite

I snapped one screw while changing a gasket on my car. I said now the DIY will cost more and more but watched a few videos and found this item.Other alternatives contained drilling bits as well. I said I need this item once in a blue moon and drilling bits that I have should do the job. After breaking one bit, I managed to make a deep dent on the screw and used the smallest extraction bit which didn't work. So tried the second smallest and it took the broken screw easily. So, I would say don't worry about the size indicators on bits getting erased some time later, it is a trial and error operation, not a precise drilling operation.I used my electric drill for the whole operation and it worked fine for me. Nice addition to my tool box which I have no idea when I ever will need it again. So I am glad that I bought this item which was cheap and consumes no space... Recommended to give a try for sure.

The size of the spark plug: m14 (check for yours in the official website, most cars have m14 though)The number of extractor: 5 (biggest one)The head(very important, I was looking for the right head for 6 days): 3/8 drive(drive doesn't matter I guess, just use for whatever drive you have), 3/8 size, 12 point socket! It fits very well, I've also rounded extractor's tail(the part that goes into the socket) with one layer of thin paper towel.Long enough extension that plugs into the sockets head.Ratchet(technically not needed that much, as you shouldn't put that much pressure on it)Steps. I had been soaking the thread for about 2 days with wd 40 (2 times per day, few drops of it, nothing crazy). At the day X, I've decided to get PB Blaster, sprayed it, waited for maybe 3-4 hours and began the process. Basically you take your tool with the extractor attached and a hammer. Hammer it down LITTLE BIT, don't even try to put a lot of strength, and start to turn counter clockwise, at first it can slide little but, but don't stop and keep turning it(I did it with my hand until I felt that extractor actually grabbed the thread and that is where I've put a ratchet and kept turning. In my case it was very smooth and I could almost do it with 1 hand, so if you feel big pressure, please stop and put more PB Blaster or whatever you use. And keep going like that slowly.Good luck

I ignored the bad reviews warning these things snap like a twig trying to save some $ - my general experience with Irwin branded tools is that you get a lot of dollar value for what you pay. Not necessarily as good as the really high end German stuff but pretty darn good. So I gave these the benefit of the doubt and bought them.They sat in my toolbox for a few months until the other day when I needed to extract a 3/16 carbon steel machine screw that the head had snapped off of in a steel gate frame. Drilled a centered straight hole with a 7/64 drill bit (all the way through the screw so depth wasn't an issue) as per the instructions. Inserted the EX-2 sized extractor and carefully threaded it into the hole. When it was well seated I used a small pliers wrench to start applying pressure and with only a moderate amount of force being applied the extractor sheared right at the surface of the hole it was inserted into. An as others have experienced, I now have a piece of hardened (though apparently not hard enough) tool steel jammed inside the screw making it impossible to drill out even with my best quality bits and a steady stream of cutting oil. At the time of writing this review I don't know exactly how I am going to get around this but as other's have said and take this seriously - DO NOT BUY THESE THEY ARE JUNK!
